4.4 Trial Operation with the Servomotor Connected to the Machine
Perform the following steps for trial operation when the servomotor is connected to the machine.
The steps are specified on the condition that trial operation has been completed in each control.
 WARNING
• Malfunctions that occur after the servomotor is connected to the machine not only damage the machine, 
but may also cause an accident resulting death or injury.
During trial operation in each control, the overtravel signals (P-OT and N-OT) are OFF. 
Take an appropriate protective action, such as activating the overtravel signals (P-OT 
and N-OT).
Step Operation Reference
1
Turn ON the control power and main circuit power and make the settings for 
mechanical configuration related to protective function such as safety function, over-
travel and brake.
When using the safety function, connect a safety device to CN8.
Note:
• When not using the safety function, use the SERVOPACK with the safety function 
jumper connector (JZSP-CVH05-E provided as an accessory) inserted. If the SER-
VOPACK is used without the jumper connector inserted into CN8, no current will 
flow to the motor and no torque will be output. In this case, "Hbb" will be dis-
played on the Panel Operator or the Digital Operator.
• When a servomotor with brake is used, take advance measures to prevent vibration 
due to gravity acting on the machine or external forces before checking the brake 
operation.  Check that both servomotor and brake operations are correct.
